Subject: mm: shmem: support large folio allocation for shmem_replace_folio()
Date: Tue, 18 Jun 2024 14:54:19 +0800
To support large folio swapin for shmem in the following patches, add
large folio allocation for the new replacement folio in
shmem_replace_folio(). Moreover large folios occupy N consecutive entries
in the swap cache instead of using multi-index entries like the page
cache, therefore we should replace each consecutive entries in the swap
cache instead of using the shmem_replace_entry().
As well as updating statistics and folio reference count using the number
of pages in the folio.
